Description

Technical Field

[0001] This invention relates to the field of human safety protection equipment technology, specifically to a smart shoulder patch that can be worn on the clothing of construction workers. Background Technology

[0002] In scenarios such as highway construction, tunnel operations, and emergency road repairs, the core safety risks faced by construction workers come from unexpected situations such as vehicles entering dangerous areas, people accidentally entering dangerous areas, and equipment malfunctions. Traditional personal protective equipment, such as ordinary reflective vests, only rely on passive reflection to provide warnings. In situations such as nighttime, low-light environments in tunnels, or high-noise construction environments, the warning effect is extremely limited. Construction workers may find it difficult to detect potential dangers in their surroundings in a timely manner, which can easily lead to safety accidents such as collisions and accidental intrusions.

[0003] While some existing improved personal early warning devices possess basic alarm functions, they still have significant shortcomings:

[0004] (1) The linkage capability is weak. Most devices can only trigger alarms independently and cannot communicate with devices such as boundary monitoring devices, intelligent cone warning lights, and construction safety robots in the construction area. When external devices detect danger, they cannot transmit early warning information to personnel in a timely manner, resulting in the problem of "disconnection between equipment early warning and personnel protection".

[0005] (2) Poor communication stability. Due to electromagnetic interference and obstructions in the construction scene, the existing equipment has a short wireless communication distance and the signal is easily interrupted, resulting in delays or loss of dangerous signal transmission and inability to cover a large area of ​​work.

[0006] (3) Insufficient wearing comfort and battery life. Some devices use heavy materials or unreasonable fixing structures, which can easily cause discomfort to people when worn for a long time. Moreover, they mostly rely on a single wired charging, and the battery life is short, which makes it difficult to meet the protection needs of all-day outdoor work. Summary of the Invention

[0007] The purpose of this invention is to provide a smart shoulder patch that can be worn on the clothing of construction workers to solve the problems mentioned in the background art, such as weak linkage capability, most devices can only trigger alarms independently and cannot achieve signal communication with devices such as boundary monitoring devices, smart cone warning lights, and construction safety robots in the construction area. When external devices detect danger, they cannot transmit early warning information to personnel in a timely manner, resulting in the problem of "disconnect between equipment early warning and personnel protection"; poor communication stability, affected by electromagnetic interference and obstructions in the construction scene, the wireless communication distance of existing devices is short and the signal is easily interrupted, resulting in delay or loss of danger signal transmission and inability to cover a large area of ​​work; insufficient wearing comfort and battery life, some devices use heavy materials or unreasonable fixing structures, which can easily cause discomfort to personnel when worn for a long time, and most of them rely on a single wired charging, with short battery life, which is difficult to meet the protection needs of all-day outdoor work.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a smart shoulder patch that can be worn on the clothing of construction workers, comprising a shoulder patch body, a first connecting plate at one end of one side of the shoulder patch body, a second connecting plate at the other end of one side of the shoulder patch body, vibration motors fixedly installed at both ends of one side of the first connecting plate and both ends of one side of the second connecting plate, two red and blue flashing lights fixedly installed on both the first and second connecting plates, warning signs fixedly installed in the middle of one side of the first and second connecting plates, a buzzer fixedly installed on one side of the first connecting plate, and a charging module provided at one end of the first connecting plate;

[0009] A smart monitoring cloth is fixedly installed in the middle of the other side of the shoulder patch body. The smart monitoring cloth includes a base cloth and a flexible sensor. One side of the base cloth is fixedly connected to one side of the flexible sensor.

[0010] A power supply module that communicates with the charging module is fixedly installed on the first connecting plate;

[0011] The second connecting plate has an intelligent system fixedly installed inside, which includes a core control module, a communication module, a positioning module, and an early warning module.

[0012] When in use, the epaulette body is made of lightweight nylon material, with an overall weight of no more than 50g. It is ergonomically designed to fit the shoulder curve. The outer side of the body has a protective coating with an IP55 protection level, which effectively prevents dust and splashes, and is suitable for dusty and light rain environments in construction scenarios.

[0013] As a further technical solution of the present invention, the communication module, positioning module, early warning module and flexible sensor are all electrically connected to the core control module, the charging module is electrically connected to the power supply module, the four vibration motors, the four red and blue flashing lights and the buzzer are all electrically connected to the early warning module, the charging module is electrically connected to the power supply module, and the flexible sensor includes a body temperature monitoring unit, a heart rate monitoring unit and a fatigue monitoring unit.

[0014] During use, the core control module acts as the control center of the equipment. It receives external danger signals transmitted by the communication module, analyzes and processes the signals, and sends control commands to the early warning module to trigger multi-form early warnings. Simultaneously, it monitors the power supply module's status in real time to ensure stable equipment operation. The red and blue strobe lights use SMD3528 packaged LED beads, located on both sides of the front of the epaulette body. Under the command of the core control module 221, they emit high-frequency alternating red and blue flashes, providing strong visual penetration in low-light and complex environments to alert surrounding personnel and equipment. The vibration motor 3 is a miniature silent vibration motor, embedded in the epaulette body close to the shoulder. When triggered, it generates a 5000rpm vibration, ensuring that personnel can perceive danger through touch even in noisy construction environments. A high-decibel buzzer is located on the edge of the epaulette body 1, with a maximum decibel value of 80dB. Under the control of the core control module, it emits a continuous buzzing sound, forming an auditory warning and further enhancing the danger alert effect. The communication module uses a LORA wireless communication unit, communicating with the core control module... Electrical connection; the communication module is compatible with the LORA wireless communication protocol, operates at a frequency of 433MHz, and has an effective communication distance of no less than 1KM in open environments. It establishes a stable wireless connection with external devices such as intelligent cone warning lights, boundary monitoring devices, and construction safety robots, enabling real-time reception of danger signals such as vehicle intrusion, boundary crossing, and equipment tipping. The communication module has a built-in anti-interference filter circuit to resist electromagnetic interference in construction scenarios such as large machinery and high-voltage lines. The signal reception sensitivity reaches -148dBm, ensuring "zero delay and no loss" in the transmission of danger signals. Even in the enclosed environment of a tunnel, the communication stability can still maintain more than 95%. The power supply module is a built-in 600mAh lithium polymer rechargeable battery, electrically connected to the core control module, providing stable power to the entire device. Under the normal warning mode with intermittent operation of flashing lights, vibration, and buzzers, the working time is no less than 12 hours, meeting the power needs of all-day outdoor operation. The charging module includes a DC5V wired charging unit, electrically connected to the power supply module; the charging interface adopts Micro-USB. The Type-C interface is located in a concealed position on the side of the epaulette and is equipped with a waterproof and dustproof plug. It supports 5V / 1A charging specifications, and the charging time is no more than 1.5 hours when fully charged. It also has overcharge protection and short circuit protection functions to prevent damage to the device due to abnormal voltage during charging.

[0015] As a further technical solution of the present invention, a plurality of thermoelectric fibers are fixedly installed on the other side of the flexible sensor, and a plurality of triboelectric sensing fibers are arranged crosswise in the middle of the plurality of thermoelectric fibers, and the other side of the base fabric is fixedly connected to the epaulette body.

[0016] When in use, thermoelectric fibers are flexible materials that directly convert heat energy into electrical energy. Their core function is to collect and convert energy based on the thermoelectric effect. Thermoelectric fibers can continuously generate electricity by utilizing the temperature difference between the human body and the environment, providing power for low-power devices such as sensors and health monitors, reducing dependence on external batteries. Triboelectric sensing fibers generate current through contact charging and electrostatic induction when subjected to mechanical stimulation such as pressure, tension, or bending, enabling real-time monitoring of environmental changes or human movement without the need for an external power source.

[0017] As a further technical solution of the present invention, two fixing straps are fixedly installed on the surface of the epaulette body, and fixing rings are fixedly installed inside the two fixing straps. An elastic band body is fixedly installed at one end of each of the two fixing rings. A male buckle is fixedly installed at one end of one elastic band body, and a female buckle is fixedly installed at one end of the other elastic band body. The male buckle and the female buckle are correspondingly arranged.

[0018] When in use, the user pulls on the elastic band to adjust the distance between the male and female buckles, thereby securing the epaulettes to the point of use.

[0019] As a further technical solution of the present invention, a Velcro fastener is fixedly installed in the middle of one side of the intelligent monitoring cloth.

[0020] When in use, the Velcro has strong adhesive properties, and the epaulette itself is attached to the application point via Velcro.

[0021] As a further technical solution of the present invention, two symmetrically arranged positioning cloths are fixedly installed at both ends of the other side of the epaulette body, and an elastic shoulder strap is fixedly installed between the two opposing positioning cloths.

[0022] When in use, the user slips the epaulette onto the area of ​​application using the elastic shoulder strap.

[0023] As a further technical solution of the present invention, fixing screws are fixedly installed on the four corners of the other side of the shoulder patch body, and the shoulder patch body is fixedly connected to the first connecting plate and the second connecting plate respectively by fixing screws.

[0024] When in use, the user tightens the fixing screw. The threads on the surface of the fixing screw match the threads on the inner wall of the epaulette body, so the fixing screw rotates and translates relative to the epaulette body, fixing the first connecting plate and the second connecting plate to the epaulette body.

[0025] As a further technical solution of the present invention, one end of the epaulette body is threaded with an assembly screw, the epaulette body is fixedly mounted with an assembly plate by the assembly screw, and an alligator clip is fixedly mounted on one side of the assembly plate.

[0026] When in use, the user screws on the assembly screws. The threads on the surface of the assembly screws match the threads on the inner wall of the assembly plate, so the assembly screws rotate and move up and down relative to the assembly plate. The assembly screws fix the assembly plate to the epaulette body. The user then presses the alligator clips to put the epaulette body on their body.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. Through a triple warning system of red and blue flashing lights, vibration motors, and high-decibel buzzers, covering the three sensory dimensions of vision, touch, and hearing, it can ensure that personnel can perceive danger within 1 second, even in low-light and high-noise construction environments. At the same time, it supports graded warning modes, taking into account both safety reminders and work efficiency, and effectively avoiding the problems of "over-warning" or "under-warning".

[0029] 2. Long-distance anti-interference communication, ensuring no signal loss: Utilizing LORA wireless communication technology, it provides stable signal transmission over a 1km open area and features a built-in anti-interference filter circuit to resist electromagnetic interference in construction scenarios, achieving a signal reception success rate of over 98%. It can seamlessly integrate with various devices such as intelligent traffic cone warning lights and boundary crossing monitoring devices, forming a dual protection system of "area equipment early warning and personal reminders," eliminating the risk of "equipment and personnel protection being disconnected."

[0030] 3. Lightweight and comfortable to wear, making work "burden-free". Made of lightweight nylon material, the overall weight does not exceed 50g. Combined with ergonomic design, it fits the shoulder curve. Equipped with Velcro and alligator clips for double fixation, it is compatible with different types of work clothes and does not affect the operator's bending over, raising arms and other work movements. It achieves a balance between "safety protection" and "convenience of work" and solves the pain points of traditional equipment being "heavy and uncomfortable, affecting operation".

[0031] 4. Short charging time and long battery life make it more worry-free to use. The 600mAh battery supports 12 hours of regular warning battery life and 72 hours of standby battery life, meeting the needs of all-day construction. The Type-C fast charging interface is equipped with a 1.5-hour short charging time and a power level visual reminder function, so construction personnel do not need to frequently check the power status. The overcharge and short circuit protection design further improves the safety of equipment use and reduces maintenance costs. Attached Figure Description

[0053] When in use, the Velcro 13 has strong adhesive properties, and the epaulette body 1 is attached to the place of use by the Velcro 13.

[0054] Two symmetrically arranged positioning cloths 11 are fixedly installed at both ends on the other side of the shoulder epaulette body 1, and an elastic shoulder strap 12 is fixedly installed between the two opposing positioning cloths 11.

[0055] When in use, the user attaches the epaulette body 1 to the area of ​​use using the elastic shoulder strap 12.

[0057] When in use, the user screws the fixing screw 9. The threads on the surface of the fixing screw 9 match the threads on the inner wall of the shoulder badge body 1. Therefore, the fixing screw 9 rotates and translates relative to the shoulder badge body 1, fixing the first connecting plate 2 and the second connecting plate 8 onto the shoulder badge body 1.

[0058] One end of the epaulette body 1 is threaded with an assembly screw 20. The epaulette body 1 is fixedly mounted with an assembly plate 19 by the assembly screw 20. An alligator clip 21 is fixedly mounted on one side of the assembly plate 19.

[0059] When in use, the user screws on the assembly screw 20.

[0060] In this invention, the core control module 221 uses an STM32L431 microcontroller, which features low power consumption (standby power consumption ≤5μA), stably receives danger signals from the communication module 222, and completes parsing and triggers an early warning within 1 second; it also supports power monitoring and graded early warning control, adapting to various early warning scenarios; the red and blue flashing lights 4 in the early warning module 224 use SMD3528 packaged LED beads, with a single bead brightness ≥50lm and a flashing frequency supporting 5-15 times / second; the vibration motor 3 uses a miniature 3.7V silent motor, with a vibration intensity supporting 3000rpm and operating noise ≤30dB; the buzzer 6 uses a piezoelectric buzzer 6, with a decibel value supporting 80dB, meeting the auditory warning requirements in different noise environments; the communication module 222 uses an SX1276LORA chip, with an operating frequency of 43 3MHz, receiving sensitivity -148dBm, communication distance up to 1.2KM in open environment; built-in CRC cyclic redundancy check mechanism to ensure signal transmission accuracy, anti-electromagnetic interference capability meets GB / T17626.3-2016 standard; power supply module 23 and charging module 7, the power supply module 23 uses a 600mAh 3.7V lithium polymer battery, energy density ≥450Wh / L, normal warning mode strobe light 5 times / second, medium vibration, 70dB buzzer with 12h battery life; the charging module 7 uses TP4056 charging management chip, supports 5V / 1A charging, has automatic power cut-off and short circuit protection when the charging voltage is >4.35V, and trigger protection function when the short circuit current is >2A, the charging interface is Micro-USB Type-C, equipped with silicone waterproof and dustproof plug;

[0061] During highway maintenance and construction, workers attach smart shoulder patches to the shoulders of reflective vests using Velcro 13. When a vehicle illegally enters the construction area, the on-site boundary crossing monitoring device sends a "Level 1 High-Risk Signal" to the smart shoulder patch via LoRa communication. The core control module 221 analyzes the signal within 0.5 seconds, triggering the warning module 224: the red and blue flashing lights 4 flash at high frequency, the vibration motor 3 vibrates strongly at 3000 rpm, and the buzzer 6 sounds at a high dB level. Workers simultaneously perceive the danger through sight, touch, and hearing, and immediately evacuate to a safe area. At the same time, the communication module 222 of the smart shoulder patch can send a linkage signal to the surrounding smart cone warning lights, triggering the cone warning lights to flash at high frequency, further expanding the warning range and avoiding secondary dangers.

[0062] During tunnel construction, due to dim lighting and enclosed space, workers secure smart shoulder patches to their workwear cuffs using alligator clips 21. When a construction safety robot detects a risk of structural collapse ahead, it sends a "Level 2 Warning Signal" to the smart shoulder patch via LoRa communication. The core control module 221 triggers a combination of red and blue flashing lights, a weak vibration at 3000 rpm, and a low-decibel 70dB buzzer. Even in the noisy tunnel environment, workers can clearly perceive the warning through the vibration and light, and slowly move to a safe area. Simultaneously, the smart shoulder patch's battery monitoring unit alerts workers by flashing a red light three times (remaining battery <20%). During breaks, charging via the Type-C interface for 1.5 hours restores full charge, ensuring continuous protection for the equipment during subsequent operations.
